Well, it's starting to look like I may have to build my underhood harness from bits of multiple harnesses.

I found a 2000 Excursion harness, but the engine plugs and wires were hacked off during engine removal. After in-depth study of wire diagrams, it looks like I can just get a pickup harness and combine it with the aforementioned damaged Excursion harness to get what I need- and do it for about 50 bucks.

I also notice that there are a few Ebay sellers who just sell the fuse/relay box with the wiring harness hacked off of it.

So my question is- how do you remove the wires (including the terminal ends) from the fuse/relay box? I've fiddled around with my burned up parts and can't seem to figure it out.

 

There usually is a tab that you have to pop in order to slide the connector out. Sometimes a wedge has to be removed to access the tab, much like the connectors.

 

If that's the case, I'm just not seeing it. I'll keep digging at it.
